TLV320AIC3107 Power ON/OFF sequence

Hi Hirata-san,

Are you looking at Power Supply Sequencing or Register Sequencing?

We don't have much info on Power Supply Sequencing. We do have a recommended power sequence for the AIC3104 which can be found here on page 18:

http://www.ti.com/lit/ds/symlink/tlv320aic3104.pdf

The AIC3104 used the same core as the AIC3107 so it should be about the same.

For register sequence we have this app note here:

Again, this is the same core and is register compatible with the AIC3107.

Best Regards,

Hi Dave-san,

Thank you for your reply.

I felt AIC3107 use same core of AIC3104.

And I looked Power Supply Sequencing and Register Sequencing of AIC3104 and AIC3107 before this question.

AIC3107 have SPVDD, however AIC3104 don't have SPVDD.

Please tell me how to set power sequence of SPVDD.

Best regards,

Hirata
